CHARLES E. BLAIR, or soMnnvILLn, MASSACHUSETTS, ASSIGNOR 'ro AMEarcAn wAnP-nnAwNc MACHINE COMPANY, A CORPORATION or MAINE,

To all whom t may concern Be it mown that I, CHARLES E. BLA1R,'of Somerville,.in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Varp- Drawing-In Machines, of which the following is a speci'c'ation.

This invention has for its object the provision of means in consequence of which the drop-wires or the metallic heddles of a loom may be threaded upon the warp 't has beenheretofore proposed to prof vide a machine for automatically drawing the warp into the flexible heddles formed of cords or the like, in which the eye 'of the heddle was open and in position to receive the drawing-in needle. Such mechanism, however, is inapplicable for drawing the` warp into fiat metallic heddles or dropwires, Owing to the fact that suoli drop wires or heddles are arranged in their supports with their fiat faces substantially parallel to the line of directionof the Warpthreads. In drawing the warp into such metallic heddles or drop wires itis necessary that thedrop wire or heddle lshould be presented with its face at an angle tothe line of movement of the drawing-in needle or to the warp-thread, so that saidthread may he passed through the eye thereof.

Consequently, one feature of the present invention consists of means for automatically presenting the drop-wires or heddles successivel;7 in position for the drawing-in of the warp-thread- This' drawing-in operation may be accomplished by an operator with the aid of .the common implement which is manually used, or it maybe accomplished by an automa-tically-operated needle, as set forth in the patent to Field, No. 600,670, dated March 15, 1898.

ln the embodiment Ofl the invention which is illustrated upon the accompanyingdrawings, the drop Wires or heddles are removed from their supports in the loom, and are placed in a magazine from which they are caused tobe presented in succession ina predetermined position for the drawingan Reference is to be had tothe accompanying drawings, forming a part of this specilication, in which,.-

Of'dropwire which is particularly adapted for em ployment inv conjunction with the drawingin machine hereinbefore referred to, Fig. 19 illustrating a pair of such drop-wires. F ig. 25 illustrates another forni of drop-wire which may be employed .for Athe same purpose. Fig. 2G represents in perspectiveview some drop-wires, one or more heddles, and a warp-thread which vis being )passed through one olA the drop-wires and one of the heddles.

(ln he drawings is ill isti-ated onl that portion of thi` invention which includes the 5 mechanism for presenting the drop-wires or heddles in position l'or the drawingdn of the warp-threads, and it 'includes a magazine or receptacle for the heddles `or drop-l wires. means for feeding them from the i0 magazine. and a holder lor the drop-wirel or and are so actuated that the heddles are dropped singly to the holder. v

The machine Villustrated in the Ldrawings is adapted to act upon independent detached heddles. These are herein representedy as flat' metallic heddles of the ykind usually 3G formed out of thinresilient sheet metal and employed in the loom" as drop heddles or drop wires. The invention, however, contemplates independent detached heddles of other forms and' construction whether used as heddles or drop wires and also similar loom elements,the term heddle as well as the term @drop wire7 being used in ay generic sense to include both classes of devices.

In the drawings-ti represents the sup- 40 porting frame which is provided with bearings a in which is journaled the warp-beam if having the warp a3 thereon.

ci* Il represent horizontal guide-rods secured at each end to the frame, 'and upon flwvhich is mounted a carriage a, which is adapted to be moved step-by-step lengthwise of the machine to distribute the drop wires iat proper intervals, as will be hereinafter described.A Upon the carriage c5 is detaehably mounted the magazine or receptacle I) which contains the drop wires L. Said magazine is best shown in Figs. 3, 5 and 9, and consists of a plate detachably secured to the car-A riage by bolts b3 3. To the plate Il is secured vertical rods or guides 7; bywhich the drop wires are held in crossed relation as shown. The upper endso' the rods (f1 are secured to a removable cap i/r" by nuts b, 50 said cap having aeentral depending guiderod L? passed through the eyes LS in the drop wires. the arrangement beingsuch that the rod L7, in conjunction with the rods D, -is enabled to hold the drop wires in the proper position to be fed therefron'i, VThe plate b is provided with diagonal slots or openings w (see Figs. Il, and 7) which register with conipleniental openings in the carriage, so

that the drop wires have free passage therethrough when permitted to drop one at a time b v the feeding maehanism.

lpon the carriage is mounted the mechanism for feeding the drop wires, which includes crank-shafts (t d journaled in bear-` ings l2 if: il il, secured to thewarriage.

l Said crank-shafts are provided with crankdisks d" having crank-pins il towhich are journaled connecting rods d, the lower ends of which are connected to the outer ends of arms dT formed on short shafts dsjouifnaled in bea rings d upon the carriage. The shafts il* have formed thereon on secured thereto blades or detente il il" llo tlm, which act as supports for the drop-wires Aalternately and are so arranged through their f connections with the crank-disks that but two of the detents are operatedto support the drop wires in the magazine at the same time, best shown in Figs. 9 and 10. It will be seen that by reference to the last-mentioned figures that the .diagonallyoppositedetents d" il" act in unison to support the drop wires,vwhile the detents di [llo act in unison to yrelease the drop wire at the bottom of the pile, so that at each movement of the dete'nts, their position is reversed, the detents l rl assuming the supporting position, and the detents Il (Z9 assuming the releasing position. The alternate releasing of the drop wires is effected byplacng` each drop wire `in the magazine at an angle'to thei one below it, so that the bottom drop wire always rests upon one pair of detents and supports the pile above it, and as the detents are alternately swung downward, the drop wires are released one at a. time. Thecrankshafts dT d which operate the detente are provided with bevel gears e c meshing with bevel gears ec on a shaft c2. One of the crank-shafts d is provided with an extension c on which is mounted a pinion e* meshing with a pinion c mounted on a shaft f e journaled in bearings on the frame i Oli one end of theshaft c6 is mounted'a pinionl meshing with a pinion es mounted on a shaft e" join-nailed in bearings on the frame u.. v The shaft c is rotated step-by-step by means of aratchet mfinounted on theouter end thereof, said ratchet being engaged by a springpawlf on the inner sideof an arm f', as shown in Fig. l, The arm f is loosely y mounted at its upper end on the end of the shaft c, its lower or free end having a connecting rod suitably attached thereto, the other end of which engages a disk f3 mounted on a stud f* secured to the frame, said disk heilig provided with a wris"pin f25 to which said outer end is attached. narm.

so shaped tnat as the drop-wire emerges from it, it is given a quarter turn on its longitudinal axis, and remains'wi'th its faces at right angles to its former position.

The drop wires, as they are fed tothe holder, are required to be placed in the slots alternately. To effect this end I have placed in the conduit a deflector Z which is secured to a shaft Z vprovided with an arm Z2 attached at its outer or free en to. a rodjZa. Theupper nd of saidrodis provided with a rollZ" adapted to bear'- against a cam Z5 on the shaft c2. The de ression of the treadle by the operator caus s the shaft c2 to make a partial rotation of the cam, which causes the defiector to assume the position shown in dotted Vlines in Fig. 1, and the neXt partial rotation of the shaft causes the cam to recede from the roll, thus permitting a spring ZI (the lower end of which bears upon the carriage and the upper end against a collar Z7 secured to therod Z3) to raise the rod so that the detlector is carried to the opposlte position, as shown in dotted lines in Fig. 4

and in full lines in Fig. 18.

It will be observed from Figs. 1, 2, and 4, l

that' the frame is provided with hooks or supports fn, for the reception of the harnesses,

indicated at o o.: and, further, that the warpthreads d3 pass from the beam a2. upward and over the cross-bar p and thence downwardly to a comb p', where they are detachably secured. In operation, where the warpthreads are drawn in manually, the operator passes a suitable implement thropgh the first heddle, through the drop-wire which is vin the holder, and engages the lirst warpthread, drawing it forward through the drop-wire and through the heddle. the foot-treadle f7 is depressed, and another drow-wire is released in the magazine and is dropped in position,the threaded-dropwire having been previously .transferred .from the holder to one of the grooyes ha. This operation is repeated, again tand again, until a1l.. of the Warp-threads have been drawn through the drop-wires and through the heddles in the two harnesses. The drop-wires are separated alternately into the two grooves of the receptacle 71,2, so that they are ready to be carried therefrom by passing bars through the eyes thereof motion.

T hen.

when the threads are drawn taut, after the warp has been exhausted in the loom, the drop-wires may be brought into the same horizontal line, and each alternate drop wire may be easily separated from the adjacent drop Wires, soas to arrange said drop wires in angular or crossed relation, as indicated in Fig. 9. It should be understood that the drop-wires are conventionally shown in Figs.

13, 14 and '15 wherein they are illustrated as open or separated so as to be easily seen, but it-is plain that the drop-Wires can be brought into alinement by loosening the warp-threads m2 and moving the drop-wires longitudinally of the same into alinement. It is desirable, however, at times to provide for the drop-wires being easily separated or arrangedirlangular relation, and to this end, I have shown in Figs. 19 to 24, inclusive, drop-wires each of which is provided with a member or projection 1' on one side with an aperture fr. By placing these drop-wires in the loom` initially, with 'the members'r projecting alternately forwar arid rear- Ward, they may be removed from the m .I

upon a rod spassed through the eyes thereof, after which rods s s maybe-passed. through the apertures 7" and the drop wires easily placed in angular relation to each other, shown in Figs. 23 and 24. vIt is not essential that the members r should be of any particular shape, it simply being necessary that each alternating drop-Wire should be distinguished from the "adjacent drop wires, and to secure this end, the thread eyes r2 may be located a little to one side of the central longitudinal line thereof, so that, in thatv event, when the rod s must pass through the eyes, the drop wires can be easilyminoved into the angular relation desired. such a formation, the member on the `drop'wire can consist ofthe slightly larger portion to one side of the eye. Instead of having the member at the upper end of the vdrop-wire, the member r canl be formedv on the lower portion thereof, as shown in Fig.` 25.

I believe it to be novel to form drop-Wires which are alternately distinguishable from those between them, either by broadening one side of the drop wire, or by lengthening the alternating drop wires, and I havecontemplated employing these forms in carrying out my invention.

.I do not herein claim theA structural:

characteristics alone of the heddles herein disclosed nor of a series of heddles assem? bled in the relations described except in com- 1 bination with the mechanical means for co- I- divisional application, Serial No. 824,249, filed March 12, 19145. i
